RAILWAY-SIGNAL.

SPECIFICATION .forming part of Letters Patent N o. 678,818, dated July 16, 1901. Application lied October 20, 1900. Serial No. 33.778. .(No model.)

To all whom it may concern:

Be it known that I, MILLARD FILLMORE AW'ALKER, a citizen of the United States, re-

siding at Flatonia, in the county of Fayette and State of Texas, have invented a new and useful Railway-Signal, of which the following is a specification.

The invention relates to improvements in railway-signals.

'The object of the present invention is to improve the construction of railway-signals and to provide a simple and comparatively inexpensive one adapted to utili z e the light of a telegraph-cnice otlestructure and capable of honsin'ga'ndgprtecting the parts and of being readily operated for displaying either a white or colored light.

The linvention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings,'Figure 1 is a perspective view of a railway-signal constructed in accordance with this invention. Fig. 2 is a 1ongitudinal sectional view. Fig. 3 is a horizontal sectional view. Fig. 4. is a transverse sectional view on line 4 4 of Fig. 2. Fig. 5 is a detail perspective view of the cap of the outer end of the box or casing, illustrating the arrangement of the mirrors.

Like numerals of reference designate corresponding parts in all the figures of the drawlngs.

1 designates a box or casing designed to extend through the wall of a telegraph-oftice or other structure, with one end arranged within the structure and its other end on the exterior of the same in order that the light of the office may be utilized for illuminating nightsignals. The box or casing, which is preferably rectangular in cross-section, as shown,

' v may be constructed of any suitable material and maybe mounted in proper position above the track in any suitable manner, and it is provided at its inner end with an opening 2, and it has lateral openings 3 at opposite sides of its outer end. The box or casing is provided at the openings 2 and 3 with plano-convex lenses, and a light 4 is designed to be interposed between the inner end of the box or casing and a reiiector 5, which throws a light through the end opening 2 into the box or casing. The lens 6, which is located at the inner end of the box or casing, has its convex face at its outer side, and the lenses 7 at the sides of the box or casin g have their plane faces at the inner sides. The rays of light thrown into the box or casing by the reflector are reflected through the side openings 3 by a pair of mirrors 8, mounted on the removable end or cap 9, which closes the outer end of the box or casing. The mirrors,`which are arranged at right anglesto each other, are each arranged at an angle of ninety degrees to the plane of the outer face of the end or cap 9, and they are adapted to reflect the rays of light through the side lenses at right angles to the length of the box or casing. The cap or end piece 9 is provided with triangular top and bottom pieces 10, forming supports for the mirrors, and the said cap or end piece is adapted to be readily removed to aiord access to the interior of the box or casing for cleaning the mirrors or for cleaning or changing the colored slides, hereinafter described.

The outer portion of the box or casing is provided at opposite sides with upper and lower ways 11 and 12, receiving colored slides 13, of glass or any other transparent material. The slides are connected bya transverse bar 14 and are provided with suitable frames to receive the transparent material, and the said transverse bar isprovided at its center with a perforated ear 15, which is detachably pivoted by a suitable fastening device to a recip` rocating rod 15, and when it is desired to change the color of the slides the cross bar or piece '14 is detached from the rod; but instead of removing the slides in this manner any other suitable provision may be made for changing the colored glass or other material. The longitudinal rod 15, which slides in a longitudinal groove 16, hasits rear portion extended through a slot 17 of the bottom of the box or casing, as clearly shown in Fig. 2 of the aocompanyingdrawings. This exterior rear portion of the rod passes through a suit able guide 18 and has disposed on it a spiral spring 19, which is interposed between the said guide 18 and a suitable stop 2O of the rod and adapted to maintain the signal in one position and to return it automatically to such position after it has been operated and is free -Fvfir" the signal.

4o by the said cap,

to move.Y The stop 20 m'ay consist of a collar or flange, and the rear end 21 of the rod isl bent at an anglevandhas a cord 22 or other flexible connection attached to it. This cord 5 extends forward over a,pulley 23, which is mounted beneath the box or casing at one side or. the reciprocating rod, and the said cord may extend from the said pulley to any desired point, and when pulled it is adapted ro to reciprocate the rod against the action of the coiled spring for carrying the colored slides over the lenses for displaying a colored signal. The cord may be secured in any suit-- able manner for retaining the colored slides I5 at the apertures or openings of the sides of the boxor casing, and when it is released the coiled spring will operate automatically to return the slides to their initial position.

It will be seen that the railway-signal is zo exceedingly simple and inexpensive in construction, that it is positive and reliable in operation, and that the light of an oice or the like may be utilized, thereby 'dispensing with a lamp or other illuminating means for It will also be apparent that the parts are housed within the box or casing or arranged within the office or other structure,

so that the signal is not aiected by the weather, and that ready access may be had 3o to the interiorpf the box or casing for cleaning the parts or changing the slides. What is claimed is- 1. A railway-signal comprising a casing provided at its inner end with an opening and having side openings at its outer end, a

2. A railway-signal comprising a casing provided at its inner end with an opening and having side openings at its outer end, a removable cap or cover fitted on the outer end of the casingand provided with triangnf- 'lar supports located at-itsinner face, the mir-'f a spring engaging the rod to hold the slides in one position, operating mechanism con-v nected with the rod and adapted to reciprocate the same to change the position of the slides, and mirrors arranged Within'the.casing, substantially as described.

4. A railway-signal comprising a casing provided at its inner end with an opening and having side openings at its outer end, colored slides arranged to cover the side openings, a cross-piece connecting the slides, a reciprocating rod extending from the crosspiece, a spring for holding the slides in one position, and operating mechanism connected with and adapted to'reciprocate the rods to change the position of .the slides, substantially as described.

In testimony that I claim the foregoing as 8c;L

my own I have hereto afxed my signature in the presence of two witnesses.
